56  BOTANICAL  AND  PHARMACOLOGICAL  INQUIRIES. 
Benzoin  or  Gum  Benjamin. — Obtain  complete  specimens  of  the  tree 
which  affords  this  drug  in  Siam. 
Cardamoms. — The  so-called  Wild  or  Bastard  Cardamom  of  Siam  is  pro- 
duced by  Amomum  xanthioides,  Wallich,  a  plant  of  which  complete  and  well- 
preserved  specimens  are  requested  in  order  that  it  may  be  described  and 
figured. 
The  seeds  per  se  have  been  imported  into  England,  while  the  empty 
capsules  are  found  in  the  drug-shops  of  China.  Are  the  latter  exported 
from  Siam  to  China  ? 
What  is  the  origin  of  the  cardamom  called  by  the  Chinese  Yang-chun- 
sha,  the  Hairy  China  Cardamom  of  pharmacologists  ?  It  is  said  to  be  pro- 
duced in  the  province  of  Kwang-tung,  and  it  may  be  a  native  of  Cochin 
China. 
Nothing  is  known  of  the  origin  of  the  scitamineous  fruit  to  which  the 
name  Large  Round  China  Cardamom  has  been  given,  and  which  is  known 
to  the  Chinese  as  Tsaou-kow.  The  same  remark  applies  to  the  Bitter-seeded 
Cardamom,  Yih-che-tsze,  and  Ovoid  China  Cardamom,  Tsaou-kwo  or  Qua- 
leu  ;  it  is  probable  that  all  of  them  are  productions  of  the  south  of  China, 
or  of  Cochin  China. 
Cassia  Bark. — Specimens  are  much  desired  of  the  tree  which  affords 
this  bark  in  Java,  on  the  Malabar  coast,  in  the  south  of  China,  and  in 
Cochin  China.  Botanical  specimens  should  in  all  instances  include  good 
samples  of  the  bark,  young  and  old,  obtained  from  the  same  tree. 
Cassia  Buds.— •These  are  the  immature  fruits  of  a  Cinnamomum,  native 
of  Cochin  China,  specimens  of  which  are  requested. 
An  inferior  kind  of  Cassia  Buds,  known  as  Lovengoopoo,  is  found  at 
Madras.    What  is  the  species  that  affords  it? 
Aromatic  Barks  of  other  Laurinece,  as  Culitlawang,  Massoy,  Sintoc,  are 
objects  of  commerce  in  the  Indian  Archipelago,  and  are  but  imperfectly 
known  in  Europe.  The  traveller  should  embrace  the  opportunity,  when  it 
occurs,  of  seeing  the  bark  collected,  and  of  obtaining  authentic  specimens 
of  it,  and  of  the  tree  yielding  it. 
Massoy  Bark  is  produced  on  the  west  coast  of  New  Guinea. 
Galangal  Root. — Endeavor  to  procure  the  plant  affording  this  drug,  which 
is  imported  from  the  south  of  China. 
Elemi. — This  resin  is  abundantly  produced  in  the  forests  of  the  Philip- 
pines, where  it  often  assists  in  giving  a  cheerful  blaze  to  the  fire  of  the 
traveller.  It  is  also  exported  from  Manilla  as  a  drug.  The  tree  that 
affords  it  is  probably  a  Canarium,  but  it  is  desirable  to  have  complete 
specimens  in  order  to  ascertain  the  species  with  exactness. 
Elemi  is  also  produced  in  Mexico,  where  it  is  known  as  Copal;  it  occurs 
in  commerce  in  scraped  pieces,  which  are  semi-cylindrical,  yellowish,  semi- 
opaque,  and  having  the  usual  strong  and  fragrant  odor  of  Elemi.  This 
drug  is  the  produce  of  Elaphrium  elemiferum,  Royle,  a  tree  occurring  near
